Evolved node b reconfiguration method, user equipment and evolved node b

Abstract

The present disclosure provides an eNB reconfiguration method, a UE and an eNB. The eNB reconfiguration method includes steps of: receiving, by a UE, from an MeNB an RRC reconfiguration message carrying an RRC reconfiguration parameter of an SeNB and an RRC reconfiguration parameter of the MeNB; when the RRC reconfiguration parameter of the MeNB is ignorable, not returning to the MeNB a message, or returning RRC reconfiguration result information of the SeNB to the MeNB; when RRC reconfiguration for the MeNB has been completed, returning to the MeNB an RRC reconfiguration success message carrying the RRC reconfiguration result information of the SeNB; and when an abnormality occurs during the RRC reconfiguration for the MeNB, initiating RRC reconstruction for the MeNB. According to the present disclosure, it is able to process RRC parameter parallel configuration for the SeNB.

1 - 3 . (canceled) 
     
     
         4 . An evolved Node B (eNB) reconfiguration method, comprising steps of:
 receiving, by a Master eNB (MeNB), from a secondary eNB (SeNB) a Radio Resource Control (RRC) reconfiguration message carrying an RRC reconfiguration parameter of the SeNB;   transmitting, by the MeNB, to a User Equipment (UE) an RRC reconfiguration message of the MeNB carrying the RRC reconfiguration message from the SeNB, the RRC reconfiguration message of the MeNB further including an RRC reconfiguration parameter of the MeNB; and   when the MeNB has received RRC reconfiguration result information of the SeNB from the UE, returning, by the MeNB, to the SeNB an RRC reconfiguration result in accordance with the RRC reconfiguration result information of the SeNB.   
     
     
         5 . The method according to  claim 4 , wherein the step of returning to the SeNB the RRC reconfiguration result in accordance with the RRC reconfiguration result information of the SeNB comprises:
 when the RRC reconfiguration result information of the SeNB is RRC reconfiguration success information of the SeNB, returning, by the MeNB, to the SeNB an RRC reconfiguration success message; and   when the RRC reconfiguration result information of the SeNB is RRC reconfiguration abnormality information, returning, by the MeNB, to the SeNB an RRC reconfiguration abnormality message.   
     
     
         6 . The method according to  claim 4 , further comprising when not receiving the RRC reconfiguration result information of the SeNB, not returning to the SeNB the RRC reconfiguration result. 
     
     
         7 . An evolved Node B (eNB) reconfiguration method, comprising steps of:
 when a Master eNB (MeNB) has received a Radio Resource Control (RRC) reconfiguration message of a secondary eNB (SeNB), parsing the RRC reconfiguration message of the SeNB;   when parameter configuration acquired by parsing the RRC reconfiguration message of the SeNB is acceptable, forwarding, by the MeNB, to a User Equipment (UE) the RRC reconfiguration message of the SeNB, and returning an RRC reconfiguration success message to the SeNB after RRC reconfiguration for the SeNB has been completed successfully; and   when the parameter configuration acquired by parsing the RRC reconfiguration message of the SeNB is unacceptable, transmitting, by the MeNB, to the SeNB an RRC reconfiguration abnormality message.   
     
     
         8 . The method according to  claim 7 , further comprising, when the RRC reconfiguration message of the SeNB is ignorable, not performing any processing by the MeNB, or transmitting to the SeNB a notification message notifying that the RRC reconfiguration message of the SeNB is ignorable. 
     
     
         9 - 15 . (canceled) 
     
     
         16 . An evolved Node B (eNB), comprising a processor configured to:
 when receiving an RRC reconfiguration message of a secondary eNB (SeNB), parse the RRC reconfiguration message of the SeNB; and   when parameter configuration acquired by parsing the RRC reconfiguration message of the SeNB is acceptable, forward to a User Equipment (UE) the RRC reconfiguration message of the SeNB and return an RRC reconfiguration success message to the SeNB after RRC reconfiguration for the SeNB has been completed successfully, and when the parameter configuration acquired by parsing the RRC reconfiguration message of the SeNB is unacceptable, transmit to the SeNB an RRC reconfiguration abnormality message.   
     
     
         17 . The eNB according to  claim 16 , wherein the processor is further configured to, when the RRC reconfiguration message of the SeNB is ignorable, not perform any processing or transmit to the SeNB a notification message notifying that the RRC reconfiguration message of the SeNB is ignorable. 
     
     
         18 . (canceled) 
     
     
         19 . The method according to  claim 5 , further comprising when not receiving the RRC reconfiguration result information of the SeNB, not returning to the SeNB the RRC reconfiguration result.
